Hello — I am glad you stopped by.

Engineer who never stopped typing.

I write code most days, and recently figured out that one experienced engineer with the right AI setup can ship like a team of ten. Having more fun building software in 2026 than I did in 1998.

30+ years building software · 50+ production AI systems shipped in the last 16 months · named inventor on a U.S. patent filing · NASA- and journal-published

It runs on my own stack, in my own voice, and it knows the whole story — papers included.

The Short Version

Chapter 1

I was supposed to be a mechanical engineer.

Six years at MIPT in Moscow studying applied mechanics and the theory of elasticity. Then a PhD at NC State on digital modeling of composite materials — never finished, because somewhere between simulating textile composites and writing my first compiler, the compiler won.

Chapter 2

Founded Tizbi in 1998 to keep writing code.

Bootstrapped a software firm with my co-founder Jim. 28 years later it's a global team. Funny thing — I never stopped writing code myself. Best way I know to lead engineers is to ship alongside them.

Chapter 3

Then 2025 happened.

Claude Code landed. I built an operating layer around it — memory, skills, prompts, agents. Now I ship at a pace that used to need a whole team. The fun isn't slowing. If anything, I'm building more confidently than at any point in 30 years.

What I'm Building

HumanData — RAG over 18,000+ customer calls at FlameOFF Coatings. Claude reads the schema, writes SQL, runs it, interprets the answer — "RAG without vectors" over a 490,000+ record store at roughly $0.10–0.30 per query.

Saxila / MoverEstimator — A "Human Language" interface: ask in plain English, Claude writes and runs the SQL and explains the answer. Schema lives in 158 description rows, so new tables become queryable with zero code changes.

Validation Gate — Guardrails for an agentic system, hardened by adversarial red-team campaigns. One campaign caught a fail-open exemption I then closed; 169 unit tests, regression clean.

Architect Search — Autonomous lead-discovery agent. Claude + web search, runs unattended; 8,789 architects and 1,571 firms classified across 900+ cities.

AI Operating Layer — the meta-project. Persistent memory, 150+ domain skills, MCP integrations, multi-tenant prompt architecture, centralized token store. The reason all the above ship fast.

Tizbi Customer Portal — .NET 10 multi-tenant ops hub. 10+ sub-applications, one login, database-driven access control.

SEO-Kombain — Multi-source analytics pipeline pulling from 5 sources into 35+ Azure SQL tables every night, with AI strategy briefs layered on top. Solo build, end to end.

Writing & Publications

Two strands, thirty years apart. In the early 1990s, at the Latvian Academy of Sciences and then NC State, I published on the computational mechanics of composite materials — optimal design, three-dimensional stress fields, finite-element and spline methods — in peer-reviewed journals, a NASA contractor report, and a Chapman & Hall volume. I'm also a named inventor on a U.S. patent filing from my early platform days. More recently I'm co-authoring a white paper on AI-native software development built on my operating layer.
